It does pivot!! I was afraid I had miss judged and it wouldn't. Trying to decide if I should worry about mounting the middle feet. The Tiger system doesn't have feet in the center and the rivets would interfear with the tramp slot and possibly damage the tramp. The other four feet are beyond the slot. Do I need the center attachment points?
It depends on the radius your jib swings through - but probably not. As long as the traveler car is not putting stress on the center of the self tacker when sheeted, you should be fine. The only time the traveler is ever there is when it is swinging to the other side and the loads should be very small at that point. Do you have a bigger picture?
